Finite-difference procedures are used to solve axisymmetric thermal stress problems with aid of digital computer; elasticity theory is employed in stress-function formulation that includes effects of continuously varying temperatures in axial and radial directions; use of these techniques permits details such as curved boundaries and multimaterial assemblies to be incorporated into computer program; experimental test program was developed concurrently and solutions are compared with photoelastic model studies and with measurements made on complete propellant-grain systems; solutions to propellant-grain problems are presented.
